My friend Erica, who is just as much of a DIYer as I am, mentioned to me that she made envelope pillow covers for her bedroom. Although I've seen them before, I'd never heard of an envelope pillow cover. They looked interesting enough, so I thought I'd give them a try. There are a couple things that I particularly like about them:

You don't have to be that exact and precise in your measuring. I measured the fabric using a tape measurer for the first pillow. For the second, I just kind of laid my pillow form on the fabric and eyeballed it.

They fit really snug around the pillow form.

Even if you make them slightly smaller than the pillow, they fit, taking on the shape of the pillow form that was inserted.

They can be removed and washed (depending on the washability of the fabric you use). This was a MAAAJOR plus over the pillows I'd recently done. Since I don't know how to insert zippers yet, I would just sew the pillow form inside the pillow cover, meaning the only way I could take the cover off to change it or wash it, would be to cut it off.

They're cheap!! Both of the pillows above were made using less than a yard of fabric a piece. Usually fabrics that are less than a yard are placed in the discount bin at fabric stores. These are marked down considerably. It's possible to do the pillows above with about a dollar or two of fabric.

I didn't document my process step by step nor take pictures along the way. I was just trying to make sure I got the covers made. After making them, which averaged a time of about 15-20 minutes per pillow, I just had to share this awesome, quick, really cute project with you. I found >>this blog post<< online that I used to show me how to make them. At first it was a bit hard to follow but I eventually caught on. You can also look up tutorials on Youtube that may provide better or more detailed visuals.
